This invention relates to paper boxes and in particular to the type provided with an edge extension.

A particular object of the invention is to produce at a minimum cost and with a minimum number of operations and material, a paper box which. will have all of the characteristics of paper boxes heretofore manu-' factured for use in the candy trade, and in the boxing of other commodities in which practice has decreed the use of a box and cover therefor, each having the bottom extended beyond the body of the box on all four sides thereof.

In the box industry, it is well known that the making of an extension edge box is one of the most difficult in the trade. Many operations are necessary in order to provide a fancy candy box which is usually decorated in some appropriate design, the parts of which fit together to provide a strong and neat appearing receptacle.

In the manufacture of boxes, heretofore, it was necessary, first, to procure the cardboard in squares and then score the same transversely and longitudinally. The next step was the cutting out of the corners and bending up the sides and then, the staying up of the corners by means of paper strips which were glued on the ends and sides to form the corners of the box. The fifth step in the process was the putting on of an extra bottom of material which was sufiiciently large to extend beyond the limits of the sides and ends of the box. This extra bottom had to be'glued on and then formed, what will be hereinafter termed as the extension edge. The next step in the process was the wrapping of the entire box with fancy paper which was glued on or otherwise secured to the body of the box and which took considerable time in order that the same be posi tioned properly over the parts of the box.

The important object of our invention, therefore is to eliminate a great many of the steps in the making of a paper box by providing a blank wherein all cutting and scoring will be done in a single operation and to also provide a blank which, when glued, may be bent to form the edge extensions, after which the entire box is comleted in one bending operation and the box Blank may be printed in fancy design in order to eliminate the subsequent covering thereof with a design paper.

To enable others skilled in the art to fully comprehend the underlying features of our invention that they may embody the same in the various modifications in structure and relation contemplated, a drawing depicting a preferred form has been annexed as a part of this disclosure and in such drawing, similar reference characters denote correspondingrpar-ts throughout all the views, of which,

igure 1 is a view in perspective of a box and its cover incorporating the features of our Invention.

Figure 2 is a top plan View of the blank used to make the entire box or lid with the scoring thereon which indicates the bending point of the blank.

Figure 3 is an enlarged view in perspective showing one of the bending operations in the construction of our box.

Figure 4 is a sectional view taken on the line 44 of Figure 1 showing how the edge extension is formed and how the sides of the box are locked together, the connecting means being covered by the outer end portion, and

Figure 5 is an enlarged cross section through the extension edge of the box showing how the same is glued in position.

Referring to the drawings in detail 5 indicates a box and 6' a lid therefor, both the box and the lid being made in the same manner with the exception that the box lid is made slightly larger to fit over the box itself. As has been before stated, one'of the objects of box makers has been to provide a single blank of which may be made a box having an edge extension, the box being made from a single piece with a minimum number of bending and gluing operations, and in order to accomplish this end, we have provided the blank indicated by the numeral 7 which consists of a bottom portion 8, the corners thereof being cut as at 9, the blank itself defining the end extension 10 and side extensions 11. The end extensions, or as they might better be termed, the ends 10 are scored longitudinally with three score lines, 12, 13 and 14, the lines 12 and 13 constituting end extension scores while the score line 14 defines the point at which the end is bent to provide an inner end portion and an outer end portion, they being designated respectively by the numerals 15 and 16. The blank is also provided with the sides 11 hereinbefore referred to, which are scored longitudinally to provide the side extension scores 17 and 18, a score being also provided, as indicated by the numeral 19 to define the bending point of the inner and outer side portions 20 and 21 respectively, the outer side portion 21 cut to provide an extended hook tab 22 at one end and at the op ite end, a loop tab 23, the hook tab 22 belng cut out to provide the hook 24 which is engaged when the box is bent to its folded position by a flexible loop 25 which is secured in an opening 26 in the loop tab 23. It is of course understood that the hook tab 22 will be engaged by the loop 25 disposed in the transversely opposite loop tab 23 and that in referring to the outer and inner side portions 20 and 21, the sides of the box are referred to, the bending of all of the sides are the same.

It is evident that this blank cut and scored as described, which may be done in one operation, provides a blank which may be immediately bent to provide side extensions. This is done by bending the sides 11 and 10 along the score lines 17 and 12 respectively and when this has been done, the ends and sides are again bent on the score lines 13 and 18 respectively to form the side extensions, or as they may better be termed, the edge extensions 26. In order to retain the sides and ends in their folded position, we may glue the blank in that portion lying between the score lines 17 and 18 and between the score lines 12 and 13 on both sides and ends of the box blank, as shown in Fi ure 5, when bending has occurred, as hereinbefore stated, the outer end portions and the outer side portions will be in vertical position, being articularly illustrated in Figure 3, in whic 1 the edge extension 26 have been glued in position against the bottom 8 and outer and inner end portions and side portions shown in vertical position, thus, after this gluing and bending has been completed, the opposite loop and hook tabs are secured together through the medium of the loop 25 holding the sides of the box together r1 'dl thereby providing a strong box w ich cannot be readily torn and which, b the weight of its contents, will not be roken easily during handling or shipment. When the tabs have been connected, as described, the inner end portion 15 and the inner side portions 20 are bent inwardly on the scored lines 14 and 19 respectively and it will be noted in Figure 3, when the side portions are bent inwardly, the end portions are then bentin to conceal the loop and hook tabs and their connecting elements 25 and after this bending of the inner end portions and the inner side portions have been completed, the box is in its finished state and is ready for assembling with its cover, and the usual fancy apron piece may be secured user in flat condition thereby reducing bulk and consequently shipping charges and which can be bent up to completed shape by the user.

It is evident also that we have provided in a single blank, means whereby an extension edge of double thickness may be provided which will retain its shape and which will enhance the appearance of the box.

It is also evident that we have provided box blank which may be rinted on one or both sides and which wil, when folded in completed condition, present a pleasing appearance, will be strong in construction and will meet substantially all of the requirements of such a container.

While we have illustrated and described our invention with some degree of particularity, we realize that in practice various alterations therein may be made. We therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended claim.

Having thus described our invention, what we claim as new and desire to secure by United States Letters Patent is A container blank includin end and side wall members having lines o scoring so ar ranged that when the blank is folded to form the container, portions of said members at opposite sides of a corresponding one of the score lines in each of said. members will overlap and form an edge extension, portions of each of said members at opposite sides of another corresponding score line being foldable to overlapped relation, tabs at the ends of one of the last mentioned ortions of two relatively opposite wall mem ers foldable to fit between the said overlapped portions of the other wall members, one of said tabs havin a hook, and a loop connected with the ot er tab and engageable with said loop of the companion tab whereby to connect companion ones of said tabs and prevent relative outward displacement of the wall members of which the tabs form a part.

In testimony whereof we afiix our signatures.
